We lost power today, for some 20 to 30 seconds. It was enough for my computer however, since as a full-blown desktop computer it doesn't have a battery like those laptops, and I was always too cheap to invest in a UPS backup power system to protect my computer from things like power outages. Anyhow... when I managed to get my computer back up running and all, I noticed I didn't have sound anymore. Had to do some hacking, and I eventually managed to get pipewire (the sound server) running again. So to prevent this from happening again, I wrote a simple script that checks whether pipewire is running or not, and restarts it if it's not. Since I had had a recurring problem of losing my Finnish keybindings and the Wacom drawing tablet also seemed to forget that I'm left-handed, I also added some magic to set things right, and in some cases, left. So in the end, this is what I created, in `~/.config/qtile/autostart.sh`: ``` #!/bin/sh LOGFILE=~/.config/qtile/autostart.log echo "Starting autostart script at $(date)" >> $LOGFILE # Function to check if a process is running is_running() { pgrep "$1" > /dev/null 2>&1 } # Check and Start PipeWire if not running if is_running "pipewire"; then echo "PipeWire is already running" >> $LOGFILE else echo "Starting PipeWire" >> $LOGFILE pipewire & notify-send "Qtile" "PipeWire started" sleep 1 # Delay for 1 second fi # Check and Start WirePlumber if not running if is_running "wireplumber"; then echo "WirePlumber is already running" >> $LOGFILE else echo "Starting WirePlumber" >> $LOGFILE wireplumber & notify-send "Qtile" "WirePlumber started" sleep 1 # Delay for 1 second fi # Set keymap to Finnish echo "Setting keymap to Finnish" >> $LOGFILE setxkbmap fi notify-send "Qtile" "Keymap set to Finnish" sleep 1 # Delay for 1 second # Set Wacom tablet to left-handed mode echo "Setting Wacom tablet to left-handed mode" >> $LOGFILE ~/.bin/Scripts/wacom-left-handed.sh notify-send "Qtile" "Wacom tablet set to left-handed mode" sleep 1 # Delay for 1 second # Send a notification echo "Sending notification" >> $LOGFILE notify-send "Qtile" "Autostart script executed" ``` It logs everything too, ain't that cool? So, after the script was written, I set it as an executable: `chmod +x ~/.config/qtile/autostart.sh` To run it from inside Qtile every time the configuration is refreshed with `Ctrl+Mod4+r` (Mod4 is usually the "Windows" key on many PC keyboards), I added these hooks (the parts that start with `@hook.subscribe.`) into the qtile configuration that is in `~/.config/qtile/config.py`: ``` import os # <-- This had to be added from libqtile import bar, layout, widget, hook from libqtile.config import Click, Drag, Group, Key, Match, Screen from libqtile.lazy import lazy from libqtile.utils import guess_terminal import subprocess @hook.subscribe.startup_once # Only runs at initial startup def autostart_once(): home = os.path.expanduser('~') with open(home + '/.config/qtile/autostart.log', 'a') as f: f.write("Running autostart hook\n") subprocess.call([home + '/.config/qtile/autostart.sh']) @hook.subscribe.startup # Runs every time Qtile is 'refreshed' def autostart(): home = os.path.expanduser('~') with open(home + '/.config/qtile/autostart.log', 'a') as f: f.write("Running restart hook\n") subprocess.call([home + '/.config/qtile/autostart.sh']) # Rest of the configuration below ```

The darned thing didn't want to work, until I took a look at the Qtile logfile `~/.local/share/qtile/qtile.log` and noticed there was an error message about the missing `os` library module. So I had to add `import os` to the configuration too. Now it works fine.
